RPM Range

Fabricast BEST COST & DELIVERY sliprings provide a reliable method of transmitting power and data, from a stationary to a rotating component, with consistantly low electrical noise over a wide range of operating speeds. Fabricast BEST COST & DELIVERY sliprings work very well while stationary or rotating either in a single direction, or bi-directionally.

Fabricast slip rings, utilizing solid coin silver rings and silver graphite brushes, work well at high speeds of rotation. In general, the maximum RPM for Fabricast BEST COST & DELIVERY slip rings is definied by the maximum surface feet per minute the brush contact material can travel. See Fabricast catalog for different brush contact materials and respective maximum surface feet per minute ratings.

Use the following formula to calculate surface feet per minute:

Surface Feet Per Minute = (Ring Diameter in Inches x 3.141 x RPM) / 12

Please note that this is only a guideline. Maximum operating speeds may be limited by noise (dynamic resistance) requirements, brush life requirements, bearings, and various environmental conditions. For high speed applications please contact Fabricast for help in selecting the appropriate brush material, bearings, and number of brushes per ring to best meet the mechanical, electrical, and environmental specifications for your application.

Operating Environment

Fabricast BEST COST & DELIVERY slip rings can operate in temperatures from -65°F to 250°F. Please note that this is only a guideline. Operating temperature range can be reduced by high RPM and high current specifications.

Fabricast BEST COST & DELIVERY slip rings can be modified to operate in high altitude, dry nitrogen and hard vacuum environments.
